The subject of geranium bombs has come up lately here, but we also posted about it years ago. What Tehran is using are these now. Here's some old posts about it:

Here's another, tho mostly dealing with Kiev: https://8kun.top/qresearch/res/17568992.html#17569648

Russia was using these in Ukr, obviously. We've learned this past week that the whole Ukr campaign was as much a rehearsal for Tehran in any potential war with Israel/US, as it was for Ukr itself. All the Russians learned about tracking US military digitals for targeting, has been employed here for Tehran. Very deep hole, as usual. Just wanted to provide some more background.

Pepe Escobar is discussing this in this video here too.
